Granny made veggies in her pressure cooker. So, with it being Saint Patrick’s Day weekend, these recipe is in honor of my most amazing Granny.

Instant Pot Mashed Potatoes (Pressure Cooker)
I am feeling a little sentimental this week and really missing my Granny! We always had so much fun celebrating Saint Patrick’s Day!
I did Irish Dance as a child and my girls did too. Now my niece is also Irish Dancing. Always lots of events going on.
As I said my Granny’s pressure cooker was not dangerous but she always scared the crap out of me. She’d say, with her Irish Brogue, if the top blows run away! Who says that, my Granny! It never blew up but she always had me with one eye on that darn pressure cooker!
Thank goodness, Instant pots are a lot easier to use and my Granny would love using it to make mashed potatoes.

Instant Pot Mashed Potatoes FAQs:
What type of potatoes are best for making a good mash?
The best potatoes for mashing are higher in starch like Russet Potatoes or Yukon. I talk about this in my Classic Homemade Mashed Potato Recipe!
Can I make this recipe ahead of time?
The potatoes can be made early in the day and kept warm in the Instant Pot.
The recipe uses low-fat ingredients, can full-fat be used?
Sure, I tend to use low-fat ingredients when possible for my families personal preference. Full-fat buttermilk and sour cream can be used in these potatoes!
What goes well with Instant Pot Mashed Potatoes:
- Granny’s Bangers – go ahead and giggle, this recipe rocks!
- Swedish Meatballs – make these delicious meatballs and you have a great meal with these taters!
- Slow Cooker Cranberry Pot Roast: let those appliances do all the work, relax and have a beer or a glass or wine!
- Greek Lemon Chicken Thighs: from the very talented Lemon Blossoms, these thighs are so flavorful.
I don’t have buttermilk, can I still make these mashed potatoes?
Absolutely, use regular milk and add 1 teaspoon of white vinegar to every cup of milk. For this recipe I use about 1/3 cup of milk so use about 1/4 -1/2 teaspoon of white vinegar to the milk. Let it sit for about 5 minutes before using in the potatoes. You can also use plain milk, a slightly different taste but still delicious!
